I’m using a 180 degree FOV fisheye camera for a project and am having difficulty getting OpenCV to display the entire camera frame. When I open the camera in the standard Windows camera app it shows the full 180 degree FOV, but when I use a simple script to display the camera in Python it crops a decent chunk of the image and nearly halves the FOV.
Image using Windows camera app: Windows — ImgBB
Image when Python script is running: python — ImgBB
Below is the code I’m using:
import cv2
cap = cv2.VideoCapture(0)
if not cap.isOpened():
raise IOError("Cannot open webcam")
while True:
ret, frame = cap.read()
frame = cv2.resize(frame, (1500,1000), fx=0, fy=0, interpolation=cv2.INTER_AREA)
cv2.imshow('Input', frame)
c = cv2.waitKey(1)
if c == 27:
break
cap.release()
cv2.destroyAllWindows()
Anyone know how to stop this auto-cropping and display the full frame? Resizing the window doesn’t help. Any help would be much appreciated!
